to Electronic Associates, Inc., Long Branch, N.J., a

corporation of New Jersey Filed Oct. 3, 1960, Ser. No. 60,067 2 Claims.(Cl. 346138) This invention relates to recording paper or sheets, and,more particularly, to recording paper used as the recording medium of arecorder device.

In one type of recorder device, a variable parameter, such as the on-offtime of a machine, is plotted as a function of a standard parameter,such as time, by rotating a drum having recording paper thereon and bymarking portions of the paper in response to a voltage developed as afunction of the operating time of a machine to obtain a plot of thisparameter against time. In such devices it is desirable to secure therecording paper tightly on the surface of the drum and to be able toremove the recorded medium and to substitute a new one therefor withease and simplicity so that periods wherein it is desirable to recorddata are not taken up with changing from one record paper to another.

It is an object of the invention to provide a recording paper for therotatable drum of a recording device wherein the paper can be securelyfastened to the surface of the drum along an axis parallel to therotating axis of the drum so that errors are not induced into therecorded markings by misalignment of the recording paper thereon; andalso, it is a further object of the invention to provide a recordingpaper which is both installable on and removable from the surface of thedrum 'with ease and simplicity.

Another object of the invention is to provide a recording paper whichafter it becomes a recorded medium can be indexed and bound in apermanent record book for future reference.

Accordingly, the recording paper of the invention is fabricated withsuch dimensions and configuration as to enable the recording paper to bewrapped around the surface of the rotatable drum, the paper beingslightly oversized in the longitudinal direction to facilitate theattachment of the recording paper to the drum and to enable therecording paper to be permanently bound in a record notebook. Tofacilitate the attachment of the recording paper to the drum, a foldedflap with angled sides is provided at one end of the recording paper.The other end of the recording paper may also be provided with angledsides for securing that end of the recording paper in place underneaththe leading end of the recording paper forming the folded flap so thatthe recording paper can be drawn taut across the surface of therotatable drum and secured in place in a substantially small section ofthe surface of the drum.

Moreover, a perforated mark is provided in a vertical direction on therecording paper to insure that the folding edge which is used to securethe recording paper to the drum lies in a substantially verticaldirection so that the recording paper can be properly positioned on thesurface of the drum. A perforated mark can also be provided on the otherend of the recording paper for forming another folding edge, which ismore rigid than the paper itself so that it can be inserted underneaththe leading edge of the recording paper and secured thereat tightly by adevice used to secure the recording paper to the rotatable drum.Additionally, the recording paper can be inserted into a permanentrecord book by providing suitable openings in either of the ends thereofadjacent the folded edges provided in the recording paper, oralternatively, if desirable, the longitudinal length of the paper can beshortened by removing portions of the recording paper along theperforated mark provided in the recording paper.

These objects and features of the invention will be understood byreference to the following detailed description when taken inconjunction with the accompanying drawing, wherein:

FIGURE 1 is a plan-view of the recording paper of the invention;

FIG. 2 is a three-dimension view partly in section of a rotatable drumhaving the recording paper shown in FIG. 1 attached thereto; and

FIG. 3 is a side-elevation view of the drum shown in PEG. 2 with aportion of the recording paper cut away.

Referring to FIG. 1, there is shown the novel record ing sheet or paper10 of the invention. As shown the longitudinal sides 12 and 14 areappreciably longer than the vertical sides 16 and 18. The longitudinallength of the paper, however, is selected so as to enable the paper tobe wrapped around the circumference of a rotating drum 20 (FIG. 2) ofthe recording device, and the length of the paper is oversized forreasons to become apparent. The vertical extent of the paper, on theother hand, is selected so as to enable the paper to cover a portion ofthe drum which is traversed by a marking stylus. Intermediate each ofthe vertical sides 16 and 18, and the longitudinal sides 12 and 14, areangled sides 26, 28, 38, and 40.

A perforated mark 22 or series of perforations 24 is provided in avertical direction and to one side of the junction between each of theangled sides 26 and 28 provided between the vertical side 16 and each ofthe longitudinal sides 12 and 14 at the leading edge of the paper.Accordingly, when the paper is folded back on itself on the perforatedmark 22 a fiap 30 is provided with an edge 32 along which the paper canbe secured in place to the surface of the rotatable drum 20.

In a similar manner, a perforated mark 34 or a series of perforations 36is provided on the other side of the paper which intercepts each of theangled sides 38 and 40 provided intermediate the vertical side 18 andthe longitudinal sides 12 and 14. Similarly, a flap 42 with an edge 44is provided at the other end of the paper by folding the paper back onitself at the perforated mark provided therein.

Printed numbers 46 may be provided in a longitudinal direction along oneedge of the paper. These numbers may be used to identify each one of aplurality of machines having a variable parameter, such as therespective on-off time of each machine, and numbers 48 can be providedin a vertical direction along one side of the paper to identify aparameter, such as time, against which the variable parameter will beplotted. For example, the on-off time of a plurality of machines can beplotted as a function of time with a suitable recorder device in whichelectric signals indicative of the on-oif time of each of the machinesto be monitored is connected to a stylus disposed adjacent the recordingpaper on a rotatable drum to obtain a permanent record of the operationof each of the machines over a selected period of time.

A flexible band 50 is provided for securing the recording paper or sheet10 in place to the rotatable drum 20. The band 50, for example, consistsof a strip of metal which is secured at the ends thereof and extends ina vertical direction across the surface of the drum 20. One end 52 ofthe band 50 is bent back on itself so as to provide a clamp for engagingone end of the cylinder comprising the rotatable drum 20. The oppositeend 54 of the band 50 is provided with an opening 56 therein forsecuring the end 54 of the band to a surface of the drum 20.

A tension bar 58 having an opening 60 therein is positioned with theopening 60 over the opening 56 in the end 54 of the band and over amating threaded opening 62 provided in the drum for securing the band 50in place under stress after the end clamp 52 in the band is afiixed tothe other end of the rotatable drum. Additionally, the end 54 of theband may be turned back on itself so that it rests on the top surface ofthe drum 20 and functions to restrain any movement of the band 50circumferentially or in an outward direction from the surface of thedrum.

The recording paper is correctly positioned on the drum with the surfacethereof adjacent a stylus by sliding the angled side 26 or 28 under theband 50 and positioning the folded edge 32 formed along the perforatedmark 22 against a leading edge 64 of the band in enfolding relationthereto. The leading edge of recording paper 10 may be adjusted While inthis position so as to have the folded edge 32 coincide with the leadingedge 64 of the band in order to secure the paper in place in a verticaldirection. The paper 10 is then wrapped around the circumference of thedrum and the folded edge 44 at the other end of the paper 16 can beinserted intermediate the flap 30 and the surface of the rotatable drum20 so that both ends of the paper are secured in place by the band 50.It should be noted at this point that by having the angled sides 38 and40 at the trailing edge of the paper, the trailing edge can be insertedunder the ends of the band 50 wherein the pressure exerted by the bandis a maximum with greater facility than if the angled sides were not soprovided.

Alternatively, the flap 42 need not be formed along the trailing end ofthe paper if an angled side 38 or 40 can be pushed underneath the band;however, by forming the folded edge 44, there is provided asubstantially rigid surface, which can Withstand frictional contact Withthe flap 30 at the leading edge so that it can be positioned adjacentthe leading edge of the paper; and moreover, the rigidity of the foldededge enables the trailing edge to be pushed underneath the leading edgeand against the pressure exerted by the band so that the paper can bedrawn taut across the surface of the drum.

Spaced apart openings 66 may be provided in one or both of the flaps 30and 42 initially or after pertinent data is recorded thereon. Theseopenings 66 can be made to conform to the spacing of the binder in anotebook or record book. Thus, after the record of the event iscompleted the recording paper can be included in a notebook for futurereference. In lieu of providing openings in the flap 30, openings can beprovided in the flap 42 for securing the recorded paper in a notebook aspreviously indicated, and the flap 30 can be used as an indexing devicefor recording thereon pertinent data or indicia such as the date,recording hours, or any other significant data to be made of record inconjunction with the recorded event. Also the size of the recordingpaper can be shortened as needed by removing the portion of the paperalong one or both of the perforated marks.

Having described the principles of the present invention with referenceto a particular exemplary embodiment, the scope of the present inventionis to be interpreted by the appended claims, and not in any way limitedby the particular embodiment as many modifications thereof will presentthemselves to those skilled in the art without departing from theprinciples of the invention.
